Problem 1 (50 points)
You are asked to design a new eco-friendly energy system for the CityU laboratory shown in
Fig.1 below. The laboratory includes a fume hood, where experiments are conducted, a
refrigerator where reagents are stocked, an oven, and a shower. The laboratory is used by two
students that live in Kwun Tong and Tsim Sha Tsui, respectively. You observe that CityU is
characterized by excellent solar irradiance. As a sustainable energy engineer, you need to
estimate the total energy consumption of the laboratory (including the energy expenditure due
to the commute) and offset the total energy consumption with renewables.
